LAMP.

SPECIFICATION forming part of Letters Patent No. 429,181, dated June 3, 1890.

Application filed October 14, 1889. Serial No. 326,967. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE WV. IVOOD- WARD, of Brooklyn, in Kings county, and State of New York, have invented a certain new and useful Improvement in Lamps, of which the following is a specification.

My improvement relates to the wick-adj usting mechanism of a lamp.

The improvement consists in the combination, with a wick ring or carrier, of a vertically-adjustable rod, a hollow projection on the one, a hollow pair of shoulders on the other, and a U-shaped locking-pin passing through said projection and shoulders in a direction parallel with the length of the rod.

In the accompanying drawings, Figure 1 is a sectional elevation of the reservoir,burner, and outer shell of the wick-tube of a lamp embodying my improvement. Fig. 2 is a side view of the wick ring or carrier detached. Fig. 3 is a side view of a vertically-adjustable rod. Fig. 4 is a view of the locking-pin. Fig. 5 is an end view of the latter. Fig. 6 is a horizontal section of the wick ring or carrier and rod secured together. 7

Similar letters of reference designate corresponding parts in all the figures.

A A designate the wick-tube of the lamp, it being composed of two shells, the inner of 0 which A is arranged concentrically within the other and at such distance from the latter as to leave a space suitable for accommodating a wick in circular form. The inner shell forms a central-draft tube.

B designates a wick ring or carrier, consist ing, as here shown, of a tube or cylindric shell surrounding the inner shell of the wick-tube and engaging with the wick. To facilitate its engagement with the wick, it may have spurs, or be constructed in any other suitable manner.

O designates a rod serving to adjust the wick ring or carrier upwardly or downwardly. This rod is detachably connected with the 5 wick ring or carrier, and in the present instance is represented as extending therefrom downwardly, then laterally, thence upwardly through the top of the oil-reservoir D of the lamp. It is shown as having a bearing through the top of the reservoir, and this bearing receives but does not engage the rod, being sim ply a guide therefor.

The wick ring or carrier and the rod are provided with hollow portions resembling the lugs or bearers of hingeplates. As shown, there are two such hollow portions 1) b on the wick ring or carrier and one such portion 1) upon the rod. These hollow portions extend upwardly and downwardly, so that when the hollow portion of the rod is interposed be tween the hollow portions of the wick ring or carrier and in line therewith a pin E may be inserted vertically to secure them together.

It will be seen that the hollow portions bb of the wick-raising ring or carrier project outwardly from the wick-raising ring or carrier and in effect form a pair of shoulders; also, that the hollow portion 1) of the rod forms a projection which engages with the pair of shoulders or hollow portions 12 b of the wick ring or carrier in such a way that when the rod is pulled upward it will move the wickraising ring or carrier upward, and when pushed downward it will move the wick ring or carrier downward. The pin prevents the projection or hollow portion 1) of the rod from becoming disengaged from the pair of shoulders or hollow portions 1) of the wick-raising ring or carrier.

The pin E is of inverted-U shape, the two limbs extending downwardly to occupy the same point and the intermediate transverse portion converging outward, so as to form a hand-piece. One of the limbs fits in a hearing 6, with which the wick ring or carrier B is provided, and can he slid upwardly and downwardly in said hearing. The other limb is in position to pass through the hollow portions 1) b b of the rod 0 and the wick ring or carrier B.

By my improvement I provide a very simple wick-adj usting mechanism, which will permit of the wick ring or carrier being taken out with facility whenever it is necessary to remove or insert a wick.

hat I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination, with a central draft lamp, of a wick-raising ring or carrier, a rod provided with a hand-piece above the lamp- I00 all receives but does not engage the rod, said rod and ring being provided one with a hollow projection and the other with a hollow pair of shoulders,and an. inverted- U -shaped pin working in a bearing upon the wick-raising ring or carrier and passing vertically through said projection and shoulders, the transverse portion of the pin projecting outward, substantially as specified.
